Practical Atheists, who are nominal or non-practicing "believers" who live lives exactly as if they were atheists, belong to Practical Atheism.

We have discussed the growing problem of practical atheism, in American Ethos, definition of Libertarian and elsewhere herein. The "practical" atheist is the person who does not claim to be an atheist, but behaves as if he were an atheist. In the political realm, the practical atheist is the one who insists on law not addressing "moral" issues, because they assume that any legislated moral rules based on religion are restricting of liberty, which must be unrestricted.
